An ordinary bicycle is portable but slow in speed. With strengthening awareness of body-building for people, life is in a rapid pace, and people require transportation, speed of the ordinary bicycle cannot achieve speed which people need sometimes. A portable acceleration bicycle is added by a chain wheel and a flywheel and some practical and simple devices on the basis of the ordinary bicycle, so that people can ride the bicycle rapidly and flexibly in a portable manner.
